Play casino slot Thunderstruck II by Microgaming for free online
After the lionized casino game Thunderstruck from 2004, Microgaming came up with a sequel - the Thunderstruck II slot machine in 2010 (overhauled later - in 2020). Instead of 9 pay lines, the second chapter utilizes 243 win ways, still comes with Medium Volatility, but is heavily enhanced with a loftier RTP - 96.45% (compare to the 96.10% in the first chapter) and equipped with more impressive maximum potential - 480 000 CAD or 8000x the total bet (in parallel with the 3333x the total bet in the initial title). The same Norse mythology topic is exploited once more, but this time the accent is on the majestic city of Asgard and other Scandinavian notorious characters. You will encounter Thor and his famous hammer on the reels, Odin, Loki, Valkyrie, and Valhalla. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

Different modes and exciting experiences are waiting for every player who is persistent enough to walk through all the chambers of the Great Hall of Spins, and the unique (it the time of the game creation) Wild-storm feature can make from your 'thunder/lightning/wind burst' - adventure a real epic one.

Personal testers’ opinion about Thunderstruck II slot

  • Despite its ageing, Thunderstruck II slot machine is still inside of TOP 20 games of all times at most of the world charts, present at all casino lobbies in every continent, and ranks better than most contemporary games. Microgaming Company. This is one of the main reasons why you should definitely play this game (in case you hesitate, of course) - it is hot all the time, creating the best possible game foundation for WINNING: despite its volatility and unpredictability, it is ready to 'go nuts' at any moment, which cannot be said for many other slots.
  • It is always challenging to trump your own success, developing a greater bestseller. Still, Microgaming seems to have this covered by making the major hit Thunderstruck I into an even superior release - the Thunderstruck II. Regarding gameplay and features, many people see the similarity between the sister games offered by the tycoon. But here is the order of their release, clarifying that the winning 243’s streak for Microgaming began with the second edition of the Thor trilogy.

  • The graphic is decent, and the heroic music is awesome. Although the provision is not the most generous for a 243 liner, somehow, the mixture of values of adjacent symbols, doubling Wild combos, the hit probability (of over 32%) and the general waiting term between bonuses (statistically of around 168 spins) works perfectly with each other, so that by our estimations over 91% of our test sessions were winning ones. Now, that is an insane number. However, not many games can compete with such a figure. So that will say that 91 of 100 bettors here will be satisfied with the result of their game at Thunderstruck II slot machine. Below are the 14 paying symbols from the paytable info (in times the total bet):

In summary: This is one extraordinary game, which we highly recommend to all types of spinners: beginners, low-rollers, regular players, high-rollers. It is cool, enticing, and highly addictive. Be prepared with starting funs for at least 150 bets to endure until the Free Spins' opening. Your bonus progress is kept at your account history for the specific casino (so you don’t have to start all over again with gaining access to the FS), but moving to another operator will mean that you need to earn your way all over again. We pass our neutral advice to the bonus hunters. Thunderstruck II scored a middle index on our wagering mater (5.60 out of 10).
